Please help me calculate PV factor and Net Present Value for these, thank you!

a. A new operating system for an existing machine is expected to cost $531,000 and have a useful life of six years. The system yields an incremental after-tax income of $155,000 each year after deducting its straight-line depreciation. The predicted salvage value of the system is $15,000. b. A machine costs $390,000, has a $22,000 salvage value, is expected to last eight years, and will generate an after-tax income of $65,000 per year after straight-line depreciation. Assume the company requires a 10% rate of return on its investments. Compute the net present value of each potential investment. (PV of $1, FV of $1, PVA of $1, and FVA of $1) (Use appropriate factor(s) from the tables provided.) X Answer is complete but not entirely correct.

Required information (The following information applies to the questions displayed below.) Most Company has an opportunity to invest in one of two new projects. Project Y requires a $325,000 investment for new machinery with a five-year life and no salvage value. Project Z requires a $325,000 investment for new machinery with a four-year life and no salvage value. The two projects yield the following predicted annual results. The company uses straight-line depreciation, and cash flows occur evenly throughout each year. (PV of $1, FV of $1, PVA of $1, and FVA of $1) (Use appropriate factor(s) from the tables provided.)
